SUBJECT:  Utility Meter Networking (CIP# C801240) – Design Authorization 
Amount of this request:               $4,200,000 
Total estimated project cost:         $35,525,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1)  prepare design and
construction bid documents for the Utility Meter Networking project. The amount of this request
is $4,200,000 for an estimated total project cost not to exceed $35,525,000. 
EXECUTIVE SUMMARY 
The Port of Seattle (Aviation campus) has approximately 800 meters located throughout the
campus. Most of these meters do not meet updated code requirements. This project will replace 
many of the old and failing electric meters throughout the Aviation campus with the new
standard electric meters. Additionally, this project will network all the meters to a software
solution that will read and store data from the meters. New meters and networking will allow 
the Port to meet current code requirements and the Facilities and Infrastructure Utility Manager
can bill tenants as needed and can assist in the verification of the total energy demand of the
airport. 
JUSTIFICATION 
The Port of Seattle (Aviation campus) currently does not meet code requirements for electrical
meter data analysis, load, and demand evaluation. This project will satisfy the revised
Washington State Energy Code (WEC 2018, C409), Clean Building Performance Standard, and
Institute of Electrical and Electronics Engineers (IEEE) code 1547. Additionally, this project
updates many electrical meters to a new standard, resulting in improved performance across the 
Sea-Tac Airport campus. The new meters will help to ensure a stable and reliable power
distribution system by providing staff with the necessary tools to perform more effective
diagnostics and troubleshooting when power quality events occur. The improved meters and

system will also help staff target and prioritize energy efficiency improvements in support of the
Port's Century Agenda goal to be the greenest, most energy efficient port in North America. 
Diversity in Contracting 
The design services will be completed using a new project specific designer which has a 15%
WMBE aspirational goal in association to this design effort.
DETAILS 
Scope of Work 
Replace and network old and failing electric meters throughout the Aviation campus. 
(1)   The meters will be replaced (approximately 800 meters) with the Eaton PXM series
meters. 
a.  Project specific designer will be competitively procured to get design portion of
work done. 
b.  All locations are unique and will be a different design/construction based off
existing field conditions. 
(2)   Meters will also be networked into the existing Port of Seattle infrastructure. 
a.  New switches and fiber will need to be installed to connect some of the new
meters into the Port of Seattle network.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Status Quo. Do not proceed with project. 
Cost Implications: Expense approximately $100,000 for notebook development costs. 
Pros: 
(1)   Delays or defers capital investment.

Cons: 
(1)   Doesn’t update meters to meet current code requirements and pushes work off to the
future. 
(2)   Meters currently installed do not have easy replacements available, resulting in large
maintenance costs. 
(3)   Data  analysis  of  current  meters  are  cumbersome  for  billing  and  power  quality
evaluations. 
This is not the recommended alternative. 
Alternative 2 – Replace and network meters within the status 2 budget. 
Cost Implications: $35,525,000 in capital costs. 
Pros: 
(1)   Provides networking for data analysis, load, demand evaluation, and usage billing for
tenants. 
(2)   Makes meters code compliant (WEC 2018, Clean Building Performance Standard, and
IEEE 1547). 
(3)   Meters will be easier to maintain being from one manufacturer. 
Cons: 
(1)   Capital costs. 
This is the recommended alternative.
